by an upper plate or table 18 which is mounted upon the uprights 2. Keyed to the upper end of the cam shaft 12, as shown in Figure 3, is a spur gear 19 which meshes with a second spur gear 20 journalled upon a stud 21 threaded into the top plate 18. Threaded into the spur gear 20 near the periphery thereof is a stud 22 on which is pivotally mounted one end of a link 23, the other end of said link being pivotally connected to a stud 24 carried by a lever arm 25 which swings about a stud 26 mounted in the top plate 18. The bifurcated outer end 27 of lever arm 25 engages a roller 28 journalled on a stud 29, said stud being threaded into an inwardly-presented protuberance 30 of an As shown in Figure 2, the ring 31 rests upon the surface of table 18 and has its outer periphery in slidable contact with the inner base flange of a cylindrical housing 32, said housing being rigidly mounted upon the upper plate or Ytable 18 and constituting a supporting frame for the carton-conveyor which is new to be described. F or this purpose, a cylindrical frame 33 which forms a partA of the cartonconveyor, is provided with an outwardlypresented liange 34 which is slidably mounted in an inwardly-presented groove in the upper portion of stationary frame 32, said carton conveyor being thereby supported independently of'ring 31 so as not tointerfere with the latters reverse movements. Ad-

v jacent its lower edge, the traveling frame 33 is provided with a plurality of inset dog and cesses 37 is adapted to receive a ratchet pawl 42 which is pivotally mounted upon a stud 43 carried by the ring 31. Said pawl is pressed outwardly by means of a leaf spring 44 so that during clockwise movements of the drive ring 31, the cylindrical frame or support 33 is made to partake of its movement whereas during the counter-clockwise movements'- of ring 31, the ratchet pawl 42 will bedragged from the lower recess 37 and after sliding along the inner wall of frame 33, will drop into the next recess 37 in the lower series. At the end rof each counterclockwise movement of the drive ring 31, a pin 46 carried thereby, will be thrown into engagement with an inclined surface near the outer end of locking dog 39, for displacing said dog rrom rectangular recess 36 and thus releasing the cylindrical support 33 to partake of the next clockwise movement of the ring 31, Awhich thus imparts a clockwise movement tothe carton conveyor. Referring now to Figures 2,2a and 10, it will be seen that the traveling frame or support 33 is surmounted by a rigid castellated frame or structure. including raised carton-carrying plates or tables 50 which are circumferentially interposed between depressed portions 51 of the structure and integrally connected thereto by spaced uprights 52 (see Figures 2, 5 and 10). Presented in opposite directions from the uprights 52 are lugs 53 which Vcarry suitable pivots 54 for carton-gripping levers, each of said levers comprising a gripper-arm 55 provided with Yan elongated @traidor-merz? mechanism.

Referring to Figure 2a, a power shaft 177 which is journalled in bearing 178 carried by bracket` 179 which depends from the underside of table 18, carries a bevel pinion 180 which meshes'with a bevel gear 181, said gear 181 being keyed to the lower end of a vertical shaft 182 indicated in dotted lines in Figure 4. As indicated Vin 'dotted lines in said Figure 4, thev upper end of shaft 182 has a wor1n'185 keyed thereto and meshing into a wormzgear 186, saidV worm gear being"H Ieyed toa horizontal shaft'187 which is journalled in bearings 188 and 189.I A miter gear 190 which is keyed to the other endl of shaft 187 meshes into a second miter gear 191 keyed to a shaft 192 which is journalledV at opposite ends in bearings 193'an'd 194. Referring now to Figures 5 andV 7, the shaft lll) 192 has keyedthereto a. cam 195 over which Y travels a cam roller 196 journalled upon a stud 197 carried by the strap end 198 ofV a rod 199 which is pivotally connected at its other end by a pin 200 to an oscillatory crank arm 201 which is pivot'ally mounted i upon a cross-'shaft 202, A spring 203 exerts pressure on the lever arm 201 in such. a Vway as to hold the cam roller 196 in contact with the cam 195. A guide block 204 is mounted f upon. the shaft 192 in slidable ei'igagement with the walls of a longitudinal slot'205 with which the strap 198 is provided for con-` straining the movements of that end of the rod under the action of cam 195. The upper end of'crank arm 201 is provided with a slot 206 within which operates a roller 'tric ,ling pinion 223 carried by a transverse wrme 2.07 journalled upon a pin 208, said pin bering 'carried laterally `spaced bearing lugs 209 which depend from opposite edges of a 'channeled slide 210. Said roller 207 is spaced from the bearing lugs 209 by collars 211. Secured to the left end oic slide 210, according to Figure Ll, is a flattened box-like receptacle 212 Which as shown in Figures 8 'a'nd9 is provided at its inner end with a narrow discharge openingl 213, said opening being formed by inwardly contracted top and bottom portions o the Walls of said revcy p tacle. The lateral'diinension of said receptacle is also contracted vby an inward displacement or the edge vivalls21l or said receptacleto facilitate its introduction into the open end of a Acarton C presented thereto by the cart-onconveyor after one of its periodic movements. As shown in Figure il, the receptacle 212 is provided with later-` A'ally ,presented tabs 215 Ward end of slide y210 by screws 216. The slide 210 is provided fith a central longitiitlinal opening 210? and is carried by laterally-,spaced slides 2,17 vwhich rreciprocate in grooves 2.17il in side train-'es 227.

power shaft 1177 Which isjournalled in bearingl brackets 178 and 479carries a bevel 'pinien 430. Meshingjwith the bevelrpinion 480 is a 'bevel' gear L131 which keyed to a short vertical shaft 482 journalled in a ylygonal drum 262.

bearing 483 carried b a bracket arm 484 which projects lateraly from the bearing bracket 479. Keyed to the upper end ot the shortvertical shaft 482 is a large spur gear 485, said spur gear being in mesh with a small spur gear 486 (see dotted lines in Figurer 2), which is keyed vto the lower end ot a vert" cal shaft 487. Keyed to the upper end of vertical shaft 487 is a bevel pinion 488 which meshes with bevel gear 489, said bevel gear 489 being keyed to the short horizontal shatt 490 which carries the po- The lower run of said conveyor travels thru a chute 264 which terminates adjacent to a reciprocable carrier tray or chute 265 said carrier tray being provided with laterally projecting pins 266 which areV inovably engaged by the bifurcated ends 267 oit lever arms 268. Said lever arms are keyed Ato a rock shaft 269 which is journalled upon a fixed axis in laterallyy spaced frames. A crank arm 270 which is also keyed to said rock shaft, carries a Wrist pin 271 to which is pivotally connected the upper end 272 of a rod 273. Said rod is provided at its lower end with a strap 274 journalled upon a eccentric disk provided with a hub 275 keyed to power-shaft 477. A lever arm 276 which is keyed to rock shaft 269 and provided with a bifurcated outer end 277, inovably engages the oppositely presented pins 278 carried by a vertical slide 279, said slide being provided with serrations 280 at its lower end which, in the positions o1 the parts shown in Figure 2a, are disposed immediately over a forwardlypresented shelf 265a on the rreciprocatory tray 265. The operating connections for this device, arel such that the shaft 477 rotates once during the time that the conveyor 260 travels the distance between two successive lugs 261, the result being that the rock-'shaft 269 imparts a ldownward movement to slide 279 at each movement of the reciprocatory tray 265 away from the carton-conveyor. According to the present embodiment of my invention, there are six reciprocatory movements o1' tray 265 during the period of time consumed by one or the other of the charging trays 328 iii passing from lett to right (according to Figure 2a) below the reciprocating slide 27 9. 1n consequence, each charging tray 328 is loaded with siX poultices which are superimposed one upon another in the manner shown in Figures 10 and 12; For this purpose, each of said poultices is depressed by a downward movement ofl plunger 279 ast-he shelf 265a is moved `from under it.

As showny in Figure 11, a pair of laterally spaced side frames 281 are secured to the plate or table 18 by means of bolts 282, said side frames being provided with dove-tail guidesV 283 within which are reciprocably mounted slides 284, each oit' said siides being.

provided with end lugs 285. Laterally projecting studs 286 carried by the end lugs 285,

serve to journal rollers 287, saidrollers being adapted to travel to and fro in slots 288V formed in the upper ends 289 of cam-operated levers 290. rihe lower ends ofsaid levers 290 are provided with slotted ends 291 within which are adjustable-studs 292 mounted in the outer end of laterally spaced links 293 which are pivotally mounted upon the oppositely presented ends ot a bolt 294 carried by a bracket 295 on the bottom plate 1. Secured to the under side et' table 18 are a pair et depending brackets 296 provided with bearings 297 at their lower ends. Re-

ciprocably mounted in said bearings 297, are :in upper cani rod 298 and a lower cam rodV 299, the former havingran enlarged end 300 (see Figure 16) provided with a longitudinal slot 301 within which is disposed a guide block 302 en the vertical cam-shaitp12.V

Journalled upon a depending stud 303'is a cam roller 304 which travels in a cam slot 305 in the upper `tace of a Cain-disk 306.

be seen that the cam grooves 305 and 308 are adapted to impart substantially similar movements to cam rods 298 and 299, these movements, however, being Vdisplaced vone with respect to the other in an amount corresponding to 180 degrees of cam travel.

Bolted to the cam rods 298 and 299,v are .Y

blocks 312 and 315 which carry studsl 313 and 316 which pivot.in levers 290. It will be understood from this description that the slides 284 have similar cycles of movement whereby they vare alternately engaged in charging cartons presented bythe cartonconveyor. f
